Default Digital noise from speakers in flight simulator (X-Plane)

But you were talking about an "HDMI extractor." Does that have a
balanced output? I don't think so. So making a balanced connection is
off the table for you.

I have been reading all of your posts, but some of them don't make a lot
of sense, and you aren't really providing a lot of information. How
about a video or at least a sound recording of the noise that's
bothering you? We're offering common solutions to common problems, and
you might have a common problem. None of your solutions have worked. Try
something that at least has potential to work. Oh, and I think it was
Scott that mentioned capacitors.

You don't have a loudspeaker problem, you have a system problem. I could
suggest a few more tests but you seem to reject everything I've
suggested so far. I have heard of cases where certain powered speakers
that have a differential ("balanced") have a buzz problem when fed from
certain unbalanced sources. This can be fixed but there isn't a single,
guaranteed solution.

But, you know, we don't really know for sure just what noise we're
chasing. You described it as sounding like an oscillator, and when I
asked you for further details, you didn't provide any, or a recording we
could hear. That could be a clue that it is or isn't a grounding
problem. But I don't have a lot of faith in your weak computer power
supply theory unless you have one of those really high powered gamer (or
Bitcoin miner) graphics cards.
